Abstract

An apparatus includes an elongate body including a proximal portion and a distal portion. The elongate body defining a lumen. A set of sensors are disposed on the distal portion of the elongate body. An electrical connector may be coupled to the proximal portion of the elongate body, and is coupled to the set of sensors via an electrical wire extending through the elongate body. A guide member is disposed on the distal portion near the set of sensors, the guide member transitionable between an undeployed configuration and a deployed configuration. The guide member in the deployed configuration is configured to guide movement of the distal portion of the elongate body through a vascular system of a subject using blood flow. The elongate body may have a diameter less than or equal to 8 millimeters (mm).
